Specification of Letters Patent.

Patented July 24, 1917.

Application filed September 15, 1916. Serial No. 120,248.

To aZZ whom it may concern:

Be it known that I, CHnIs'rIAN WINTER, a citizen of the United States,and a resident of Oskaloosa, in the county of Mahaska and State of Iowa,have invented a new and Improved Pole-Climber, of which the following isa full, clear, and exact description.

This invention relates to climbing devices for linemen and has for anobject the provision of an improved arrangement whereby a pole may heclimbed in safety and if desired without the use of either of the hands.

Another object in view is to provide a climbing device adapted to besecured to the foot and to produce a swinging step when in use on apole.

A further object in view is to provide. a climbing device which may beclamped firmly to the foot without interfering with the usual movementof the foot when walking on the ground.

In the accompanying drawings Figure 1 is a sectional view through a poleformed with apertures therein and a front view of a pair of climbersapplied to the pole.

Fig. 2 is a side view on an enlarged scale of one of the climbingdevices.

Fig. 3 is a front view of the structure shown in Fig. 2.

Fig. 4 is a top plan View of the structure shown in Fig. 2.

Fig. 5 is a detail fragmentary view showing how the climbing device maybe used in connection with a staple.

Referring to the accompanying drawing by numerals, 1 indicates a poleprovided with a plurality of apertures 2 on each side, said pole beingshown as a metal pole though the invention may be applied to a woodenpole 3 (Fig. 5). When used with a wooden pole a staple 4 is utilizedover which the hook 5 is passed. Hook 5 is provided with a threadedshank 6 on which the nuts 7 and 8 are mounted, and then the hook isclamped to the uprights 9 in any adjusted position according to thethickness of the walls of the pole 1. The apertures 2 in the pole 1 aremade of suflicient size to readily admit the turned over part of hook 5whereby the hook may readily engage and disengage the pole. Theupstanding member 9 is bent over at the bottom and preferably extendsentirely across the flat plate 10 where a short section 11. is bent onwardly again for acting as a side brace, the part of the member 9extending across the bottom of plate 10 being held in place by suitablerivets 12.

The plate 10 is provided at the rear with heel braces 13 and 14.2 andnear the front with a strap 15 riveted or otherwise secured to the plateso that when the buckle 16 is properly adjusted the strap will fit thefoot as shown in Fig. 2, whereby the toe of the foot extends anappreciable distance beyond plate 10 thus allowing a natural movement ofthe foot when walking on the ground.

When the device is in use the climbers are arranged as shown in Fig. 1whereby they act as steps or freely swing so that the climber may adjusthis foot as desired and may climb the pole at any speed preferred. Itwill be evident that the hook 5 must be removed from one aperture andthen placed in a higher aperture in order to climb, the opposite feetacting alternately.

. What I claim is:

1. In a climber of the character described, the combination with a polehaving openings therein, of a hook member adapted to be thrust throughsaid openings, a plate for receiving the foot of a climber, said platebeing shorter than the foot of the climber whereby the front part of theclimbers foot is free for walking on the ground, an upstanding membersecured to said plate and formed with an aperture through which part ofsaid hook member projects, means for adjustably clamping said hookmember to said upstanding member, and means for clamping said plate tosaid foot.

2. A climbing device comprising a plate having braces for holding therear part of the foot on the plate, a clamping member for holding thefront part of the foot on the plate, an upstanding member having asection extending across the bottom of said plate and a lug projectingupwardly from one side so as to hold said foot against lat eralmovement, and a hook extending from near the upper part of saidupstanding member.

3. In a climbing device of the character described, the combination witha pole having apertures therein, of a foot supporting base, means forclamping the base to a foot, an upstanding member rigidly secured tosaid base and arranged on one side thereof, and a hook extending fromnear the upper part of the upstanding member for fitting into one ofsaid apertures whereby the base is supported but allowed to swing.

4;. In a climbing device of the character described, the combinationwith a pole having apertures therein, of a base, means for clamping thebase to a foot, a supporting upstanding member connected With said base,a hook adapted to be placed in any of said apertures, said hookextending through said upstanding member, a nut on each 1Q CHRISTIANWINTER.
